Media Muxer
The 3ivx Filter Suite

The 3ivx MPEG-4 5.0 Media Muxer combines MPEG-4 Audio and Video streams into an MP4 or MOV file. It supports Advanced Features such as Multiple Audio tracks, Variable Frame Rate Video, Positive and Negative Track Offsets, System Tracks, NVop Compression and Compressed Headers (also known as Fast Start for Progressive Download). In combination with the 3ivx MPEG-4 5.0 Media Splitter, the Muxer can repair broken MP4 streams generated by non-compliant MP4 File Writers or AVI codecs.

The 3ivx MPEG-4 5.0 Media Muxer comes as a DirectShow Filter that can be used in GraphEdit or integrated with any DirectShow compatible application.

Converting a MOV File to an MP4 File while adding a second Audio track.

Advanced Options

Optimize and Make Streamable
When enabled, the muxer will reposition the header information at the beginning of the stream and re-interleave the audio and video payload to minimize seeking, thus producing a streamable, fast-start MP4 file. [More]

Compress MOV Headers for Fast-Start
If checked when writing a MOV file, the muxer will recursively compress the video headers using the gzip algorithm. This can dramaticaly reduce the format overhead of a file, and decrease the pre-load time when progressively downloading a MOV. [More]

The 3ivx MPEG-4 5.0 Media Muxer is fully compliant with the ISO MP4 File Format. Together with the Audio Encoder and Video Encoder, it can generate files compatible with QuickTime 6 or later, Philips Platform4 Player, EnvivioTV and other MPEG-4 compliant players.

Together with the 3ivx MPEG-4 5.0 Media Splitter it is possible to fix malformed MP4 Files (such as those generated by early DivX 5 versions), or MPEG-4 Streams with Packed B-Frames. Other uses include the transcoding from AVI and MOV files into an MP4 file.

A COM Interface SDK for the 3ivx Filter Suite is available for our partners and professional clients. An Application Programming Interface (API) is available that allows developers to set the parameters for the various filters.
